Hmm. In the peaks it certainly still seems "enforced". But it is a
peculiarly London thing - you won't see it on, say, Merseyrail -
people will just stand still on both sides.


It can depend on how much traffic there is: the Victoria Line down escalator
at Victoria always seems to be stand both sides when I use it during the
evening peaks. Escalators shift more people if they're standing anyway.
